The evolution of a self-contained test scoring terminal is presented. The rationale for the design is presented along with an evolutionary description of the requirements for the system. The sequence of software and hardware tools, which were developed in order to build the device, are also described in this report. The resulting device, which…

Provides a step-by-step guide to creating an interactive video program, using technology that allows a computer program to control a video program, and discusses the concept, the equipment (microcomputer, videoplayer, and video interface card), and the process involved. A buyer's guide to video interface cards is included. (EJS)

NETPAD is a microcomputer-based system, implemented on a Commodore PET 2001-8, by which a human indexer can input, retrieve, and edit information in order to produce a variety of permuted index displays. The basic unit of the NETPAD system is a subnetwork (a description of a single document) containing a set of concept nodes (author, title, date,…

A proposed student model consisting of a set of programs to represent the student's knowledge state. Teaching proceeds after a comparative evaluation of student and teacher programs, and learning is represented by direct modification of the student model. The advantages of an explicit procedural model are illustrated by considering a program which…

The realization that the facilities available for the retrieval of scientific and technical information were being underutilized resulted in a project undertaken by the Drexel University School of Library and Information Science to develop a computer intermediary capable of assisting users of scientific and technical information in the performance…

BALLOTS (Bibliographic Automation of Large Library Operations using a Time-sharing System) is an on-line interactive library automation system that supports the acquisition and cataloging functions of the Stanford University Libraries' technical processing operations. The BALLOTS system is being implemented in a series of 11 modules. This paper…

The design and operation of a time-sharing monitor are described. It runs under OS/360 MVT that supports multiple application program interaction with operators of CRT (cathode ray tube) display stations and of a teletype. Key design features discussed include: 1) an interface allowing application programs to be coded in either PL/I or assembler…

The Multilingual Interpreter (MI), a language processor capable of executing more than one language, is being used at Western Washington State College to enhance interactive computing for computer-assisted instructional (CAI) users. The MI's two major functions are, first, that of scanning and translating a source language into internal…

The career decision making paradigm underlying the Information System for Vocational Development (ISVD) is briefly stated; it reflects the fact that a person has different information needs associated with different life stages, and with decision making stages within any given life stage. The greater portion of the report deals with the attempts,…

Describes a microcomputer software system designed at British Library which will interface with existing BLAISE services; e.g., offline editing of records retrieved online, stored search, and data preparation facilities. A technical description, features of system, applications programs, and the CORTEX interface with the mainframe system are…

Describes a computer-aided instruction program developed at Sheffield City Polytechnic, England, which teaches students to analyze simple sentences into their constituents and to draw tree diagrams representing their structures. Program strategy, control and operation of the programs, and evaluation are discussed. Three references and illustrative…

The need for traps, a program routine which checks the validity of the user's response to the computer's request for input, in Computer Assisted Learning Packages, is discussed. Several example traps are described. (MK)

Focusing on the use of microcomputers as "smart terminals" for accessing time-sharing systems for libraries, this document discusses the communications software needed to allow the microcomputer to appear as a terminal to the remote host. The functions which communications software programs are designed to perform are defined and…

This report documents the theory, structure, and implementation of a performance processor (written in FORTRAN IV) that can accept performance demonstration data representing various levels of operator's skill and, under user control, analyze data to provide candidate performance measures and validation test results. The processor accepts two…
